A clock does not change no matter how many differently moving observers
buzz around it.
Both its reading and rate are therefore frame independent
In other words absolute.
Since a clock counts the cycles of an oscillator, it follows that the
period of any oscillator defines an absolute interval of time.
A clock does not change no matter how many differently moving observers
buzz around it.
Correct.
Take the half-life of a muon, for instance: it is 2.197 -|s.
every 2.197 -|s, half of its population has decayed
The concept of invariant proper time is one of them.
the muon is always at rest relative to itself
What is relative is the duration measured by observers
situated "elsewhere" than the muons
even an accelerating onerCothe muon is always at rest relative
to itself; it is space that moves around it.
Take the half-life of a muon, for instance: it is 2.197 -|s.
No, Richard.
Before rebuilding relativity for the benefit of Humanity, there
is a small problem with the muon.
2.197 -|s is NOT its half-life.
It is its mean lifetime tau.
The decay law is
N(tau) = N0 exp(-tau/tau_mu)
with
tau_mu ~= 2.197 -|s.
The half-life is therefore
T_1/2 = tau_mu ln(2)
~= 1.523 -|s.
So this is also wrong:
every 2.197 -|s, half of its population has decayed
After one mean lifetime, the surviving fraction is
exp(-1) ~= 0.368,
not 0.5.
About 63.2% have decayed.
After 1.523 -|s, 50% have decayed.
A clock does not change no matter how many differently moving observers
buzz around it.
Correct.
And neither does a ruler.
If ten observers buzz around a 1-metre ruler, the ruler does not
physically change ten times.
Congratulations: we agree that changing reference frame does not
physically modify the object being described.
Both its reading and rate are therefore frame independent
The first does not imply the second.
You have quietly omitted:
rate WITH RESPECT TO WHAT?
Along the clock's own worldline it records its proper time tau.
Of course everybody can agree that between two events on that worldline
the clock recorded, say,
Delta tau = 1 second.
That quantity is invariant.
But an observer using coordinate time t assigns the rate
d tau/dt.
Another inertial observer uses t' and assigns
d tau/dt'.
There is absolutely no logical reason why these ratios must be equal
merely because the physical clock itself hasn't changed.
In SR,
d tau/dt = sqrt(1-v^2/c^2).
Different observers assign different v and different coordinate times,
while agreeing on the SAME proper time recorded by the SAME clock.
There is no contradiction.
Here is the Newtonian version of your mistake.
A car's odometer does not change when different observers buzz around
it.
Its reading is perfectly well defined.
Does it follow that
dx/dt
must have the same value in every frame?
Obviously not.
The object is unchanged.
Its coordinate velocity is frame-dependent.
In other words absolute.
No.
You have confused
invariant proper time
with
absolute universal time.
Those are almost opposite ideas.
Proper time is attached to a particular worldline.
Newtonian absolute time would assign the same elapsed time independently
of the worldline.
Calling the former "absolute" does not magically turn it into the
latter.
Since a clock counts the cycles of an oscillator, it follows that the
period of any oscillator defines an absolute interval of time.
No again.
Suppose the oscillator makes exactly N cycles between two events A and B
on its worldline.
Everyone may agree:
N = 9,192,631,770
and therefore that this clock accumulated one second of proper time.
But different inertial frames need not assign the same coordinate-time interval to A and B.
That is precisely what Lorentz transformations describe.
Your argument is therefore:
1. Changing coordinates doesn't physically alter an oscillator.
True.
2. Therefore every frame must assign the same coordinate-time
interval to its oscillations.
Doesn't follow.
You have confused changing the CLOCK with changing the COORDINATES used
to describe the clock.
And there is a wonderfully simple test of your "absolute oscillator
period" idea.
Take two identical atomic clocks.
Separate them.
Make them follow different trajectories.
Bring them back together.
Now there is only ONE frame needed for the final comparison.
If they display different elapsed times, buzzing observers have nothing whatsoever to do with it.
The clocks are sitting next to each other.
Read them.
That is why relativistic clock experiments are so devastating to the
"it's all just what observers see" objection.
Nobody needs to SEE a moving clock running slowly.
You let the clocks travel.
You reunite them.
You compare the numbers.
Nature keeps the accounts.
Take the half-life of a muon, for instance: it is 2.197 -|s.
No, Richard.
Before rebuilding relativity for the benefit of Humanity, there is a
small problem with the muon.
2.197 -|s is NOT its half-life.
It is its mean lifetime tau.
The decay law is
N(tau) = N0 exp(-tau/tau_mu)
with
tau_mu ~= 2.197 -|s.
The half-life is therefore
T_1/2 = tau_mu ln(2)
~= 1.523 -|s.
So this is also wrong:
every 2.197 -|s, half of its population has decayed
After one mean lifetime, the surviving fraction is
exp(-1) ~= 0.368,
not 0.5.
About 63.2% have decayed.
After 1.523 -|s, 50% have decayed.
That correction aside, something rather amusing has happened.
Most of the rest of your paragraph is simply standard relativity.
The concept of invariant proper time is one of them.
Yes.
the muon is always at rest relative to itself
More precisely: at every event of its timelike worldline there is a momentarily comoving inertial frame.
Yes.
What is relative is the duration measured by observers situated
"elsewhere" than the muons
Modulo your peculiar wording, yes again.
For a muon moving inertially relative to the laboratory:
Delta t = gamma Delta tau.
The muon's decay is governed by its proper time tau.
The laboratory assigns a different coordinate-time interval t.
This is undergraduate SR.
You then rename part of this
"chronotropie interne"
but so far I don't see what new physical statement the new word adds.
And this sentence needs more care:
even an accelerating onerCothe muon is always at rest relative to itself;
it is space that moves around it.
No.
"The muon is locally at rest in its instantaneous rest frame" is
standard and precise.
"Space moves around it" is not an equivalent physical law.
For an accelerated worldline there is, in general, no single global
inertial frame in which the muon remains at rest.
There is a succession of momentarily comoving inertial frames.
But the particularly funny thing is where we have arrived:
proper time is invariant;
a clock measures proper time along its worldline;
different observers may assign different coordinate times;
the moving clock is locally at rest in its own instantaneous rest
frame.
Richard, congratulations.
You have just given Ralph a reasonably serviceable introductory lesson
in Special Relativity.
Correct "half-life" to "mean lifetime", remove "space moves around it",
and postpone "chronotropie interne" until it makes a prediction
different from the standard formalism, and I could almost use the
paragraph in a classroom.
Which makes your description of yourself as an "hyper-relativist" increasingly entertaining.
After forty years spent attacking relativity from above, you are
presently explaining its elementary concept of proper time to someone attacking it from below.
Usenet does occasionally achieve equilibrium.
Along the clock's own worldline it records its proper time tau.
Henry,
No. Read what I actually wrote.
I did NOT assume that two clocks following different worldlines
will show different elapsed times.
I said:
-a-a Take two identical clocks.
-a-a Separate them.
-a-a Give them different trajectories.
-a-a Reunite them.

There is no assumption about the result in that procedure.

Excellent idea, Maciej.
Take two identical pendulum clocks.
Keep one in Paris and carry the other to the Moon.
Reunite them.
They will disagree enormously.
Have we therefore discovered that time depends on the worldline?
No.
We have discovered that a pendulum is not an ideal clock:
No, Maciej.
A pendulum is not rejected because it gives the "wrong result".
Maciej,
You didn't answer the question.
A pendulum is known IN ADVANCE to have
-a-a-a-a-a-a T = 2*pi*sqrt(L/g).
Now you propose:
-a-a-a-a-a-a "two identical pulsar clocks."
Excellent.
Please put two identical pulsars on the table.
would you reject it if it didn't give wrong result?
take 2 identical pulsar clocks.
So far your experimental programme has been:
-a-a Atomic clocks?
-a-a-a-a-a-a No! Try pendulums!
-a-a Pendulum periods depend on g?
-a-a-a-a-a-a AHA! You reject the wrong result!

-a-a Pulsar clocks?
-a-a-a-a-a-a Remote astronomical sources and timing models.
Maciej,
"Any clocks" does not mean "any physical object humans have
ever called a clock."
So your argument is now:
-a-a "You only accept clocks suitable for measuring time
-a-a-a accurately! RELIGION!"
Maciej,
No.
I gave you the criterion BEFORE the result:
A pendulum is unsuitable because its rate has known
environmental dependencies.
And I explicitly told you I would reject it EVEN IF it
gave Einstein's predicted result.
You have now ignored that twice.
As for:
-a-a "anyone can check GPS"
Excellent.
We did.
Then I gave you NTS-2: an uncompensated atomic clock was
Uncompensated atomic clock is not there.

This is magnificent.
Uncompensated atomic clock is not there.

No.
The uncompensated NTS-2 cesium clock WAS there.
Maciej,
Because the EXPERIMENT was over.
Ah.
So now we have the complete Maciej chronology:
Maciej,
let's make this even easier.
Forget NTS-2 for a moment.
There is an experiment running RIGHT NOW.
ACES -- Atomic Clock Ensemble in Space -- is installed on the ISS.
It carries:
-a-a PHARAO, a cold-caesium atomic clock
and
-a-a SHM, a space hydrogen maser.
Its explicit scientific objectives include comparing the space
clocks with atomic clocks on Earth and testing Einstein's
gravitational time-dilation/redshift prediction.
Maciej,
you didn't answer the question.
We already know your sermon:
-a-a "There is no time dilation."
-a-a "perfect clocks are desynchronizing clocks"
-a-a "mad assertion"
-a-a "sane people"
-a-a "serious equipment"
Fine.
ACES is running NOW.
PHARAO and the space hydrogen maser are in orbit NOW.
Maciej,
Excellent.
So we have finally reached the self-sealing part.
BEFORE ACES publishes its result, you already tell us:
-a-a if it confirms relativity,
-a-a the measurements are erroneous.
Well, you say "if it doesn't it is erroneous" - after.
whether they are or not - depends on an assertion.

-a-a GPS
-a-a Galileo
-a-a atomic time standards
-a-a satellite navigation
-a-a ACES
Real systems.
Real clocks.
Real engineering.
Real measurements.
Maciej,
You keep asking for the "observable properties" of a
PERFECT clock immediately after explaining yourself that
"perfect" doesn't exist.
Congratulations. You have now refuted your own question.
An ideal clock is a MODEL.
Real clocks have observable properties:
frequency, stability, accuracy, environmental sensitivities,
systematic shifts, uncertainty, etc.
And real atomic clocks can be compared.
Now your turn.
You claim GPS, Galileo and the rest are:
-a-a "really measuring t'=t"
Excellent.
SHOW THE MEASUREMENT.
Which clocks?
Maciej,
Excellent.
You have finally asked the right question.
If the ground station says
-a-a GPS time = 22:00:00
what does the satellite broadcast?
Approximately
-a-a GPS time = 22:00:00
OF COURSE.
That is what GPS is ENGINEERED to do.
Maciej,
This is getting wonderful.
You now admit you don't know much about the other systems,
but you are willing to BET what their engineers think.
So much for "serious measurement".
But let's stay with GPS, which you chose.
You say GPS was engineered to
-a-a "fuck your mad delusions"
and measure t'=t.
Unfortunately, the engineers left documentation.
Maciej,
Forget "perfect clocks".
YOU claim GPS measures
-a-a t' = t
with real clocks.
Fine.
Now remove the engineering corrections.
Maciej,
NO ONE said that removing the correction makes the clock
"perfect".
I asked what the REAL clock MEASURES when the correction
is removed.
Maciej,
NO ONE said that removing the correction makes the clock
"perfect".
I asked what the REAL clock MEASURES when the correction

Henry,
No. Read what I actually wrote.
I did NOT assume that two clocks following different worldlines will
show different elapsed times.
I said:
Take two identical clocks. Separate them.
Give them different trajectories.
Reunite them.
Compare their readings.
There is no assumption about the result in that procedure.
They might read:
Clock A: 100000.000000 s Clock B: 100000.000000 s
or:
Clock A: 100000.000000 s Clock B: 99999.999997 s
THE CLOCKS DECIDE.
Your claim of absolute time predicts the former, subject of course to ordinary instrumental effects.
Relativity predicts the latter whenever the two worldlines have
different proper durations.
Calling this "circular logic" is rather wonderful. a
The whole purpose of doing the experiment is precisely NOT to assume
which prediction is correct.
And notice that I deliberately brought the clocks back together. No
distant simultaneity.
No telescope.
No "buzzing observers".
No argument about what somebody sees.
No need even to compare two coordinate systems at the end.
Two clocks.
One table.
Two readings.
If you want to defend absolute time, give YOUR quantitative prediction
for such an experiment and compare it with the measurements.
"Einsteinian worshipper" is not a prediction.
Nature keeps the accounts.

we're getting another result, the way we like.
Maciej,

EXCELLENT.
You have finally described what happened with NTS-2.
Procedure 1:
-a-a real cesium clock in orbit
-a-a relativistic synthesizer OFF
-a-a measure its rate against ground clocks
Result:
-a-a measured:-a-a +442.5 x 10^-12
-a-a predicted:-a +446.5 x 10^-12
Then they changed the procedure.
Procedure 2:
-a-a switch the frequency synthesizer ON
Result:
-a-a the clock rate immediately changes toward the
-a-a coordinate rate required for navigation.
And YOU point to Procedure 2 and say:
-a-a LOOK! t'=t!
Maciej, you have just explained why your own argument fails.
Yes:
-a-a change the procedure -> change the result.
No "perfect clock" is involved.
No guru decides whether the clock is good.
No result is being rejected.
Both results are measurements.
OFF -> rate difference.
ON-a -> compensated rate.
The change when the synthesizer was switched on is itself
part of the experimental record.
So please explain your alternative without screaming about
"perfect clocks":
Why did the REAL cesium clock show approximately the
relativistically predicted rate difference with the
synthesizer OFF?
And why did its measured rate change when the correction
was switched ON?
Those are measurements, Maciej.
Nature doesn't speak.
Maciej,
Good.
We have now reached the really interesting part.
You say:
-a-a "Sane people have other [measurements], giving t'=t."
Excellent.
SHOW ONE.
Your explanation of that measurement is now:
That's not an alternative physical explanation.
That's a conspiracy theory with error bars.
The ultimate arbiter is experimentation.
So let's keep that one.
Not:
The ultimate arbiter is experimentation,
except when Richard already knows where Truth is standing.
Nature gets a vote, Richard.
And unlike you, she doesn't automatically vote for the man
in the middle.
Maciej,
8th time, then:
YES.
The corrected GPS satellite clock is engineered to keep
approximately the same GPS coordinate time as the ground system.
Nobody disputes that.
Sane people have different measurements,
giving t'=t.

He probably realizes it is not the best way to describe the universe
The problem is that the best way to describe the Uniberse is not known.
Every one of the known ways fails to get right something that anotner
one does get right.

Excellent.
NAME ONE.
Not a corrected GPS clock.

Aha! You have finally made a reasonably valid point. We are a long way
from explaining everything...but Newton's approach is the most
successful.
